EDGAR W. ANTHONY, OF BOSTON, MASSACHUSETTS.

HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No.354,29'7: dated December 14, 1886.

Application filed November 30, 1883. Serial No. 113,253.

T 0 all whom it may concern:

Be it known that I, EDGAR W. ANTHONY, of Boston, in the county of Suffolk and State of Massach usetts,a citizen of the United States, have invented a certain new and useful Improvement in Heating-Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature, in which- Figure l is a vertical central section of a stove having my improvements. Fig. 2 is a horizontal section upon the line or x of Fig. 1. Fig. 3 is a horizontal section upon the line y y of Fig. 1. Fig. 4 is a vertical central section of the stove on a line at right angles to that shown in Fig. 1.

The invention relates to the specific arrangement of passages and flues in thebase of the stove,-whereby a circulation of air about the stove is effected.

Referring to the drawings, Arepresents the combustion-chamber; B, the fire-pot, and O the ash-pit. Extending downwardly from the combustion-chamber A, upon each side of the fire-pot, are the diving-fines a, which extend downwardly to the base-plate a of the stove, and backwardly in the base to the uptake a Between the base-sections of the diving-fines a and the ash-pit c is the narrow passage or chamber D, which is formed by means of the flue-plates d d d and the ash-pit wall 0. This narrow chamber or passage D has an opening, d toward the front of the stove, upon either side of the ash'pit, through the baseplate, (see Fig. 3,) and also the opening or openings cl* between the uptake-pipe a3 and the lower portion of the casing E of the stove, and in the upper plate, (2, of the base-section of the stove.

It will be observed that the cooled air enters through the openings d", and is heated between the flue-plates d d d and the ash-pit walls 0 and that the air thus heated passes out through the opening or openings (1 at the rear of the stove, and that thereby a continuous circulation about the stove is provided. It will also be observed that by this construction the heat passing through the diving-fines a (No model.)

is utilized for heating the air passing through this chamber D.

I am aware that Patents No. 4,032, to Hedenberg, and No. 48,145, to Treadwell, show and describe heatingstoves having an air-heating passage extending through the base of the stove to the top, which require a somewhat complex arrangement of fines, and I consider that the said stoves do not contain the feature of my invention, which isan improvement upon that described in my Patent No. 246,995, in that I dispense with the passage or chamber and fines below the ash-pit, and thereby cheapen the construction and reduce the weight of the stove without impairing the efficiency of the invention.

The subject-matter of this application was originally shown and described in my application filed May 7, 1883, Serial No. 94,233; but it was removed subsequently by amendment, and I do not now claim herein the present subject-matter of said application.

Iam aware, also, of the Patent No. 42,831, granted N. G. Bond, dated May 24, 1864, for a firepot, which shows a chamber surrounding a fire-pot, to which entrances are provided from below, and which has an outlet at its upper end. I am also aware of the patent to Noble, No. 225,484., dated March 16, 1880,which shows a chamber or passage in the base-section of a stove about the ash-pit, into which cold air is introduced through the lower base-plate of the stove, and from which itescapesthrough openings in the upper plate of the base-section; but as these patents do not show or describe the flue-plates d (1 d arranged in relation to the ash-pit wall 0, as shown, to pro vide a narrow passage or chamber, D, between the ash-pit wall and the base-flue, and entirely surrounded by the base-flue, which passage or chamber has the inlet-openings d and the escape-openings 01*, I consider that they do not embrace the essential features of my invention. I Y

Having thus fully described my invention,

I claim and desire to secure by Letters Patent 95 of the United States- In a heatingstove, the combination and arrangement, in the base-section of the stove, of

the base-plate a, the ash-pit wall 0, the fluebase-plate, e, having the outlets or apertures plates d d d, arranged in relation to each dflarranged in relation to the passage or chamother and t0 the outer shell of the stove and bet D as specified, substantially as described. 10 to the ash-pit wall to form the base-fiues a EDGAR W. ANTHONY.
